The tested method consisted of simultaneously injecting helium in a minimum of two locations upstream from an ultrasonic flow meter at a known distance apart. The results from this project showed the flow verification method was successful in determining the gas velocity through an ultrasonic flow meter to within ±5%. These results indicate that the tested in-situ verification method is not accurate enough to replace a laboratory flow calibration, but could be used as a field diagnostic tool. The accuracy of the results and the scatter in the data were correlated to the distance between the injection points.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367572533326,"sku":"208005","price":200.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/pr-015-19606-r01-in-situ-ultrasonic-gas-meter-flow-verification-2","provider":"PRCI Store","version":"1.0","type":"link"}
